Question

if a shopkeeper wants to give 20 discount and then 10 discount on a pen which has marked price of rs 500, how much would be the selling price of the pen.​

Answer 1

Answer:

The pen will sell in 480 rupees

Answer 2

Answer: ₹360

Step-by-step explanation:

This is the case of a successive discount.

Always remember, in these cases, you can't add the discount percents and say that the shopkeeper is giving a 30% discount. Why? It is because the second discount is on the price we get after 1st discount.

Marked Price of the pen = ₹500

First Discount (in %) = 20%

Discount (in ₹) = 20% of ₹500 = 20/100 × ₹500 = ₹100

Price after 1st discount = ₹500 - ₹100 = ₹400

Now, the second discount of 10% is on this price, i.e., ₹400. That is the reason you can't add 20 and 10.

Price of the pen after 1st discount = ₹400

Second Discount (in %) = 10%

Discount (in ₹) = 10% of ₹400 = 10/100 × ₹400 = ₹40

Price after 2nd discount = ₹400 - ₹40 = ₹360

Therefore, the selling price of the pen is ₹360.
